Esc Alpine Glaciers And Glacial Processes

Front 1

Types of glaciers

Back 1

Ice sheet:Antarctica, Greenland
Valley glacier:Himalayas

Front 2

Glacial Environment Factors

Back 2

Precipitation, Temperature, Altitude, Latitude, Relief, Aspect, Ocean Distance

Front 3

Accumulation

Back 3

All processes that add snow and ice to the glacier.

Front 4

Ablation

Back 4

All the processes that remove snow and ice from the glacier.

Front 5

Glacial Erosion types

Back 5

Abrasion, Debris Entrainment, Fracture of Fresh Rock, Glacial Plucking, Meltwater Erosion

Front 6

Till

Back 6

Sediment deposited directly by the ice.

Front 7

Outwash

Back 7

Sediment deposited by ice meltwater.

Front 8

Large Scale Erosional Features

Back 8

Cirque, Arete, Horn, Col, Truncated Spur, Glacial Trough, Haning Valleys, Paternoster lakes.

Front 9

Ice Marginal Forms

Back 9

Terminal Moraine, Lateral Moraine, Recessional Moraine

Front 10

Subglacial Form

Back 10

Ground Moraine

Front 11

Stagnant Ice Form

Back 11

Hummocky Terrain

Front 12

Glaciofluvial Form

Back 12

Outwash plain

Front 13

Arete

Back 13

a steep sided, sharp edged bedrock ridge formed by glaciers eroding away on opposite sides of the ridge

Front 14

Horn

Back 14

a pyramid shaped mountain peak formed by several glaciers eroding different sides of the same mountain.

Front 15

Tarn

Back 15

a glacier lake basin produced by scouring.

Front 16

Cirque

Back 16

an amphitheater-shaped bedrock feature created as glaciers scour back into the mountain.

Front 17

Cirque Glacier

Back 17

a smaller glacier confined to a cirque that does not extend down valley from the cirque.

Front 18

Valley Glacier

Back 18

an alpine glacier flowing in a valley.

Front 19

Glacier Trough

Back 19

erosion by an alpine glacier widening and deepening to form a glacially eroded valley.

Front 20

Paternoster Lakes

Back 20

a series of lakes in a glacial valley that are connected by a stream.

Front 21

Moraines

Back 21

formed from rock debris deposited by glaciers.

Front 22

Positive Mass Balance

Back 22

Where Accumulations are greater than Ablations.
an increase in a glacier's thickness and by increasing its total area.

Front 23

Negative Mass Balance

Back 23

Where ablations are greater than total accumulations.
results in a thinning of the glacier, a reduction of area and a decrease in volume through a retreat of the glacier terminus in an up-valley direction

Front 24

Glacier Year

Back 24

begins with the first snowfall accumulation of the fall winter season and ends after the summer ablations have ceased.

Front 25

Glacier Mass Balance

Back 25

describes the relationship between annual net accumulations of snow and ice and annual net ablations.
